Quantum Computing Overview

Hey everyone,

Would it be helpful to place more emphasis on why one would use quantum computing from the get go rather than starting from a hardware perspective?

The current beginning talks about the use of quantum computing in terms of quantum devices being operated but I would argue that the entire existence of quantum computing though is due to using quantum mechanics to better solve scalability problems that classical algorithms cannot manage.

From what I understand , if I were a reader, I would also risk "putting the word quantum in front of everything." Would it be fair to say this?

I am not sure if people agree with me on this. Thoughts? Erdabravest (talk) 00:56, 6 March 2024 (UTC)

Are speculation and plans encyclopedic?

@Aislo8858 has added content about a corporation with plans to do work on quantum computing. In my opinion these plans are "news" not "knowledge" and don't belong in an encyclopedia. Johnjbarton (talk) 15:34, 18 October 2024 (UTC)

Open Problems

A new section on Open Problems was added, but it has two major problems. First it is based on a single reference from Dec. 2024 (this month) written by a single author with no significant publication record on the topic. Second the items in this list are so briefly discussed that only someone already knowledgable on the topic would know what was said.

I think the concept of an "Open Problems" section is reasonable, but it should be backed by reliable references from within the field of study and the content should give enough background for a reader to understand how the problem is related to quantum computing.

A third major problem is that the text that was added here was cut and pasted from a copyrighted source. If information from this source is ultimately judged worthy enough by local editors to be added to this article, it should only be done so using properly paraphrased text making use of an editor's own words.

Lasers in crypto and Grover's algorithm

Why is there a picture of a green laser from French wikipedia labeled as a quantum crypto layout? The image is literally shiny but doesn't have anything to do with quantum crypto, unless it is an implied joke on smoke and mirrors.

Grover's algorithm does little or nothing to speed up vs brute force when you include circuit implementation the fact that queries must be sequential, and error correction overhead. The British version of NSA published a paper "On the practical cost of Grover for AES key recovery", Sarah D. and Peter C., UK National Cyber Security Centre, March 22, 2024 https://csrc.nist.gov/csrc/media/Events/2024/fifth-pqc-standardization-conference/documents/papers/on-practical-cost-of-grover.pdf that concludes the practical security impact of Grover on plausible quantum hardware is limited, even for AES-128.

I agree about the image and removed it. The interesting Grover algorithm paper should wait until it has either lot of citations or is discussed in a review paper. Johnjbarton (talk) 16:57, 13 February 2025 (UTC)
